Do you know how customisable firefox's UI is in ways that chrome isn't? They limited it a bit in recent years so you can no longer can easily turn the url bar and tab bar into one bar which i'm sad about but all in all most of the buttons i don't use i can remove, those i do i can add, i can change the colours, shapes and location. Chrome is ugly by default and doesn't allow me to fix it.
